The Effectiveness of Esters in Cooling and Lubricating Transmission Systems in Electric Vehicles-Dielectric Fluids

University of Leeds

Faculty of Engineering and Physical Sciences

Project Description

Energy conservation and emissions reduction have become increasingly significant for automobiles due to high energy demand, fuel economy and environmental concerns. Hybrid Electric Vehicle (HEV) technology and fully Electric Vehicles (EV) are one of the most promising solutions offering a much lower fuel consumption and considerably low emissions. Emerging new driveline configurations bring new challenges in developments of HEV/EV fluids. Many different configurations have been conceived which use different methods of cooling and lubrication. Not only are these fluids essentials for lubricating and cooling the new types of powertrains and transmissions, but they are also needed to regulate the temperature of the vehicle’s battery and power electronics. As hybrids and EVs become increasingly powerful and their battery ranges and charging speeds improve, standard fluids are unable to keep up in terms of robustness, heat resistance and cooling capacity. These conditions could be controlled by base fluid or advanced additive technology.

Funding Information

Engineering & Physical Sciences Research Council Studentships paying academic fees (£4,600 in Session 2020/21), together with a maintenance grant paid at standard Research Council rates (£15,285 for Session 2020/21) for 3.5 years. UK applicants will be eligible for a full award paying tuition fees and maintenance. European Union applicants will be eligible for an award paying tuition fees only, except in exceptional circumstances, or where residency has been established for more than 3 years prior to the start of the course. Funding is awarded on a competitive basis.

Eligibility Requirements

Applicants to research degree programmes should normally have at least a first class or an upper second class British Bachelors Honours degree (or equivalent) in an appropriate discipline. The criteria for entry for some research degrees may be higher, for example, several faculties, also require a Masters degree. Applicants are advised to check with the relevant School prior to making an application. Applicants who are uncertain about the requirements for a particular research degree are advised to contact the School or Graduate School prior to making an application.

English language requirements: The minimum English language entry requirement for research postgraduate research study is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, listening and speaking) or equivalent. The test must be dated within two years of the start date of the course in order to be valid.

Application Process

Formal applications for research degree study should be made online through the University’s website. Please state clearly in the research information section that the research degree you wish to be considered for is ‘The Effectiveness of Esters in Cooling and Lubricating Transmission Systems in Electric Vehicles-Dielectric Fluids’ as well as Dr Shahriar Kosarieh as your proposed supervisor.

If English is not your first language, you must provide evidence that you meet the University’s minimum English language requirements.
